50 Nortech triple diesel with Arnesons.

Does this mean they need the aerodynamic lift to get up on plane, or do they come up on plane on their own and then rise more with the speed? What is the typical onto-plane speed?

Bingo!

for the OP - No affiliation but VERY well known boat on OSO running in the Atlantic (west side)....

I sold that boat to him a little over a year ago. Boat cruises in the mid 60’s while sipping fuel and can do it hour after hour.

Thats bob the builders ex boat right?

Yes

formerly known as "Predator"

Just curious what mpg is at mid 60s? And top speed? Thanks

About 1.3MPG in the low 60’s and it would run mid 70’s top end. But the thing about the diesels cruising in the 60’s is that you are cruising at the same speeds as 85-95mph big block block boats cruise at.

Thanks for the info. I lalways love looking at that boat.
